Abstract: 12,019. Crown Cork Co., and Moore, E. K. May 26. Bottling; stoppering; capsuling bottles &c.- Relates to improvements in apparatus for filling bottles and similar receptacles with aÙrated or other liquids, and for closing the filled receptacles by caps or " crowns," the improvements being more particularly applicable to the machines described in Specification No. 24,219, A.D. 1901, in which the mouth of the bottle is inserted into the head of the machine and is there filled and closed or crowned. In the present invention, the support 58, Figs. 3 and 6, of the bottle-rest 88 is provided with a screw spindle 58<a>, by which the support is adjusted for bottles of different lengths. The spindle 58<a> screws into a sliding nut 85 connected by the link 57 to the arm 56 on the rocking shaft 55, which is operated, to raise the bottle to and to lower it from the filling and capping head 5, by the cam 50 engaging the roller 51 on a slide connected to a second crank arm on the rocking shaft. The rest 88 is supported by the spring 89 in the cylindrical member 90, which is in turn supported, by a spring 96 of predetermined strength, on the flange 97 of a second member 98 surrounding the lower end of the member 90. The member 90 is provided with a rod 93 having, at its lower end, a bevelled disc 94 fitting in the cylinder 95, the member 98 being provided with four hinged dogs 99, which are bevelled at their lower ends to engage with the parts 94, 95. In case of excessive pressure on the bottle, the member 93 is forced down against the action of the spring 96, and the disc 94 enters the cylinder 95, the dogs 99 then moving inwards and also descending, with the member 98, to relieve the pressure. The parts are returned to normal position by the spring 100. The spring 89 acts to prevent the bottle-neck from being forced too far into the head 5. The collar 12, Figs. 1, 2, 3, 4, and 5, by which the sleeve 4 is actuated to compress the gasket in the filling-head, to form a tight joint with the bottle-neck, is provided with shoes 12*, which bear on the frame 3, the rollers 13 on the collar engaging only with the cam-inclines 15 on the sleeve 4. The collar 12 is actuated by means of the cams 59, 60, Fig. 3, engaging respectively with the slides 61, 62, Fig. 5. These slides are connected by the lever 63, and the slide 61 is pivotally connected to the lug 64 on the collar. The gasket is tightened by the action of the cam 59, and is slackened, to release the closed bottle, by the cam 60. The filling and snift valves are operated by the cams 65, 65<a>, 65<b>, 66, 66<a>, 65<b>, Fig. 3. The various cams are mounted on the wheel 49, which is driven from the shaft 68 by suitable power. The shifting-bar 106, Figs. 3 and 4, of the driving-belt is mounted on swivel bearings or carriers 105, attached to the caps of the bearings of the driving-shaft, so that the shifting-bar can be adjusted to any desired position, within the limits of the curved slots 107, to suit the direction of the driving-belt. Tne caps or crowns 69 may be fed by hand through the shoot 70, Figs. 3 and 7, their delivery to the throat 72 of the head being controlled by the tappets 70<b>, 70<d>. The tappet 70<b> is actuated by the projection 29<x>, Fig. 5, operated by the plunger 29, Fig. 4. while the tappet 70<d> is actuated by the feed-slide 71, which is operated by the lever 71<a> from the cam 71<b>, Fig. 3, carried by the bottle-raising mechanism. The forward end 71<c> of the feel-slide is formed of rubber, and serves to close the throat 72 during filling. In the modification shown in Fig. 9, the caps are fed auto natically from the hopper 70<a>, under control of the tappets 70<e>, 70<b>, 70<d>, the shoot 70 being preferably twisted to the extent of a quarter-turn.
